Modeling E
==============


Characteristics of modeling
------------------------

Method GEOMETRIQUE is used by PROPA_FISS.


Characteristics of the mesh
----------------------------

The same mesh as that of modeling A. is used.


Tested sizes and results
------------------------------

We extract the normal (:math:`\mathit{LSN}`) and tangent (:math:`\mathit{LST}`) level set using the POST_RELEVE_T operator using the operator and we check that the maximum and minimum values remain included in the capture circle of the nodes tested around the crack front, i.e. :math:`2/3`:


.. csv-table::

    ":math:`\mathit{Propag.}i` "," :math:`\mathit{Max}{\mathit{LSN}}_{i}` "," :math:`\mathit{Min}{\mathit{LSN}}_{i}` "," "," :math:`\mathit{Max}{\mathit{LST}}_{i}` "," :math:`\mathit{Min}{\mathit{LST}}_{i}`"
    "3", "0.235", "0.397", "0.397", "0.333", "0.272"


The results obtained clearly show that the level-sets remain less than the radius in which the crack front was located. This means that the crack bottom has been correctly located by method GEOMETRIQUE.
